The consistent liquid enamel slip properties is a critical parameter at any automated wet application process.
Unfortunately enamel rheology is known to change easily under the influence of particle size, specific weight, temperature, milling additives and/or pretreatment chemicals.
Failure to maintain its properties within measurable tolerances, may result in inconsistent enamel layer thickness and eventually even enamel defects.
Do you really believe that you can “feel it” with your fingers as demonstrated on the picture below, or do you rather prefer a more precise testing method ?!
The Italian National Unification institute has published UNI 11734 as of December 6, 2018.
This standard specifies a method for measuring the hydrogen diffusion coefficient in order to determine the fish-scale susceptibility of steels, which can be used in the enamelling process. Continue reading “UNI 11734 : Determining fish-scale susceptibility of enameling steel”
Impact fusion of powder paint may cause contamination issues at the cyclone of multicolour powdercoating systems.
It is therefore advisable to inspect and if necessary clean the ducting & cyclone of your powdercoating booth regularly.

Precise powder enamel application with a robot has many benefits, such as :
– lowest specific enamel consumption
– strongly reduced over-spray
– small factory footprint
Below a short video of a recently commissioned system for baking ovens with Nordson Encore PE spray gun and Encore LT gun controller by Noto Finishing.
With ultrasonic thickness measurement, you may detect the thickness of individual layers within a multi layer coating.
This may be of great help, when troubleshooting e.g. a two coats / one fire vitreous enameling process.
See our webshop for more details about this and other film thickness gauges.
Ditmer Trading & Consulting BV has reached an agreement with Mr. Jan Post of Allied Enamel Supplies in Rozenburg to take over the sale of Remaille as of November 15, 2018.

Nordson Corporation introduce their “nLighten” technology for the Encore manual powder coating gun range.
This kit improve the visibility during application and may so reduce rework & rejects and increase efficiency & safety.
Suitable for powder paint & powder enamel operations.
Visited the Tecnargilla 2018 show in Rimini some weeks ago and saw there a new application method called “Steam Spraying”.

Depending upon the annual production volume, it might be interesting to reduce labor cost by integrating all equipment of an enameling plant for water heaters and/or solar boilers.
Such integration may be done with traditional monorail conveyors in combination with automatic transfer devices, like on the picture below.
Alternatively a so-called power & free conveyor system may be used.
This conveyor type consist of two conveyor tracks above each other.
On the lower level free cars may run, while via the power chain at the upper level the free cars may be (dis)connected and transported.
Nowadays there are P+F systems, which thanks to a very special transfer system even include the transport of products within the enameling furnace.
DTC may assist with the evaluation, which solution is most suitable for your vitreous enameling project.
